Description of problem: Fedora 28 Xfce Beta 1.1 live boot SELinux is preventing accounts-daemon from using the 'dac_override' capabilities. ***** Plugin dac_override (91.4 confidence) suggests ********************** If you want to help identify if domain needs this access or you have a file with the wrong permissions on your system Then turn on full auditing to get path information about the offending file and generate the error again. Do Turn on full auditing # auditctl -w /etc/shadow -p w Try to recreate AVC. Then execute # ausearch -m avc -ts recent If you see PATH record check ownership/permissions on file, and fix it, otherwise report as a bugzilla. ***** Plugin catchall (9.59 confidence) suggests ************************** If you believe that accounts-daemon should have the dac_override capability by default. Then you should report this as a bug. You can generate a local policy module to allow this access. Do allow this access for now by executing: # ausearch -c 'accounts-daemon' --raw | audit2allow -M my-accountsdaemon # semodule -X 300 -i my-accountsdaemon.pp Additional Information: Source Context system_u:system_r:accountsd_t:s0 Target Context system_u:system_r:accountsd_t:s0 Target Objects Unknown [ capability ] Source accounts-daemon Source Path accounts-daemon Port <Unknown> Host (removed) Source RPM Packages Target RPM Packages Policy RPM selinux-policy-3.14.1-18.fc28.noarch Selinux Enabled True Policy Type targeted Enforcing Mode Enforcing Host Name (removed) Platform Linux (removed) 4.16.0-0.rc4.git0.1.fc28.x86_64 #1 SMP Mon Mar 5 04:54:32 UTC 2018 x86_64 x86_64 Alert Count 1 First Seen 2018-03-28 00:32:54 EDT Last Seen 2018-03-28 00:32:54 EDT Local ID 621e7d58-86d2-404b-aaff-7184531edcb7 Raw Audit Messages type=AVC msg=audit(1522211574.856:114): avc: denied { dac_override } for pid=1051 comm="accounts-daemon" capability=1 scontext=system_u:system_r:accountsd_t:s0 tcontext=system_u:system_r:accountsd_t:s0 tclass=capability permissive=0 Hash: accounts-daemon,accountsd_t,accountsd_t,capability,dac_override Version-Release number of selected component: selinux-policy-3.14.1-18.fc28.noarch Additional info: component: selinux-policy reporter: libreport-2.9.3 hashmarkername: setroubleshoot kernel: 4.16.0-0.rc4.git0.1.fc28.x86_64 type: libreport
